Model IC Engine Construction Projects

Last Update: July, 2008.

I consider myself to be rather new to this hobby, especially in comparison to my compatriot Motor Boys. Nevertheless, I've managed to make a runnable engine or two and can certainly advise on what not to do! The links below go to engine project pages (and pages, and pages, and... ) on this site.

They are categorized into three levels of complexity. The classification is highly subjective. For instance the "Nano" is a very straight forward engine, but it is extremly small, which makes obtaining the correct fits difficult. And running it requires a lot of experience with compression ignition (aka "diesel") type engines, especially small ones, hence it's rated "Advanced". In contrast the Sparey 5cc diesel is a monster, but construction is sufficiently straight forward to be classed as suitable for a beginner.

If you are contemplating building an engine, see Model Engine News for October 2005 and the Engines Designed for Beginners series for my recomendations on selecting a subject.
